' application med .aug-ust is,

To all "wit-om it may concern:

Be it known that I, FRANK H. non, a citizen of the United States, residing at. Galveston, in the county of Galveston and State of Texas, have invented certain new and useful improvements in rEelephonelowing is a specilication.

This invention relates to mouthp-ieces for telephone transmitters and more particularly to a detachable disinfecting cap adapted to form a closure for the open end ot' the mouthpiece. A and prevent the transmission of `microbes or other germs lodged in the mouthpieceto the person using the telephone. l

The object of the invention ""ls to provide a comparatively simple and thoroughly etiicient device of the character described, capa- 'rorn the mouthpiece of the transmitter and by means of which the mouthpiece is rendered thoroughly sanitary.

A further object is to provide a detachable cap having a strip of cloth, paper or membrene secured thereto and saturated with a soluble germicide which will dissolve in the moist spray thrown out in talking and render the same sterile.

A further object is to provide novel means for locking the cap imposition on the mouthpiece of the telephone transmitter.

'A stillfurther vobject of the invent-ion is generally to improve this class of devices so eiiciency, as well as to reduce the cost Vot manufacture. p

Further objects and advantages will apunderstood that various changes in form, proportions and minor details of construekFor a full understandin of the invention and the merits thereof anc also to acquire a knowledgeo the details of construction and the means for eiiecting the result, reference is to be had to the following description. and

Figure 1 1s a perspective view of a telephone transmitter provided With a sanitary cap constructed in accordance with my in-l vention; Fig. 2 is a vertical sectional view of the same; Fig. S'is a perspective view of the cap with the disinfecting strip and 'locking Specicat-en of Letters etent. gtriter Jun@ 14, 1914).

member detached and shown in position to enter the rim of the cap.

Corresponding and like parts are referred to in the following description and indicated in all the views oi the drawings by the same reference characters. The sanitarjgf' disinfecting cap forming the subiect matter or" the present invention is principally des ned for attachment-,to the mouthpiece oit a telephone transmitter and by way of illustration is shown in connection with a desk telephone in which 5 designates the standard, 6 the transmitter and 7 the mouthpiece having its inner end reduced and threaded at 8 for engagement with a corresponding opening in the transmitter.

The device comprises an annular support-- ing rim 9 having its outer tace inclined toward the center of the mouthpiece 7, at 10 to form an inner circumferential iange 11 and its outer marginal edge provided with a flange 112 adapted to engage the exterior wall of the mouthpiece, as best shown in Fig. 2 ofthe drawings. rlhe metal forming the flange 12 is bent: outwardly to form a circuint'erential seating groove 13 adapted to receive a locking member 14. The' locking member le is preferably formed of a single length "of spring wire, one end of which is bent laterally-to form an angularly disposed finger piece 15 adapted to enter a recess 16 formed in the flange 12 and intersecting the groove 13. i

Interposed between the rim 9 and the adjacent edge ot the mouthpiece7, is a disinfecting cap 1'4", the latter being formed of cloth, paper, membrane or other suitable material saturated with a soluble gerrnicide which will dissolve in the moist spray thrown out in talking and render the vsame sterile. erably reinforced and strengthened by an annular strip of paper orother suitable material. 18, which latter is forced against the adjacent edge of the mouthpiece 7 when` Ithe rim '9 is positioned thereon, thereby. to-efectually prevent accidental displacement of the member 17. ln positioning the cap on the mouthpiece or" a telephone, one end of the 'wire is inserted in the groovelv with the opposite end or finger piece 15 thereof pro-A jecting through the recess 16, afterwhich the intermediate Y pressed laterally within the seating groove The cloth or membrane 17 is pret ortion of the wire is 13, thus to form a circumferential lock and Having thus described the invention, what is'claimed as new is: l

l. The combination'with a mouthpiece, of a cap engaging the mouthpiece and having a circumferential groove formed therein and intersected by a transverse recess, a strip of antiseptic material interposed between the cap and mouthpiece, and a lockin member seated in said groove and provide with an angular finger-piece adapted-to enter said recess.

2. The combination with a mouthpiece, of a cap engaging the mouthpiece and having a circumferential groove formed therein and intersected by a transverse recess, a strip of material carried by the cap and saturated with a soluble germicide which will dissolve in the moist spray thrown out in talking and render the same sterile, and a locking 'member engaging the groove in the cap and provided with an angular finger piece extend-.

ing through the recess in said cap.

3. The combination with a mouthpiece, of a cap having an opening formed therein and defining an'inwardly extending flange, there beingv a circumferential seating groove formed in the cap and intersected by. a transverserecess, a strip of lmaterial interposed between the flange and the adjacent' edge of the mouthpiece and saturated with a soluble germicide which will dissolve in the moist spray thrown out in talking and with a circumferential seating groove and having its face formed with an opening deining an inwardly extending ange, the

metal forming the cap being inclined in the direction of the mouthpiece between the outer and inner anges, there being a recess `formed in the outer flange and intersecting the seating groove, a lookin member seated in the groove and formed 0% a single length of s ring wire, one end of which is bent'lateral y -to form a linger piece adapted to 'project through the recess in said outer flange, and a strip of material carried by the cap and saturated with a solublegermicide, said strip of material being clamped in engage- .ment with the adjacent end of the mouth-' .piece by contactvwith the inclined face of the i3). As a new article of manufacture, a disinfectingr cap for telephone transmitter mouthpieces, comprising a rim having 'an inwardly extending circumferential flange and .an outer flange provided with a -circumferential seating groove, there being a recess formed in the outer ange and inter secting the groove', a strip of antiseptic ma- `terial seated in the rim, a reinforcing strip secured to said material, and a resilient lock ing member seated in the roove in the cuter.

flange and having one en thereof bent laterally to form an angularly disposed ringer p iece'extending through the recess in the rim.

In testimony whereof I athx my signature in presence of two witnesses.
